Subclaims¶
Reading the evidence codes
q is the design tier, i the impact, n the sample, and the kind with its r
the rigour judged within that kind: what each code means.
This claim: no standardized effect is recorded in observations/ for it yet, so no benchmark reading is possible.
q2 i? Average EEG amplitude differs significantly between some learning stages within each task (lectures: Stage 1 vs 2 and 1 vs 3; labs and quizzes: Stage 1 vs 2 and 2 vs 3), and between tasks at Stage 1 and Stage 3; the paper does not report a significant task difference at Stage 2. → Hui Xie 2025

q2 · i? · associational · r1
Wilcoxon rank sum tests on average amplitude of all electrodes across the semester-long simulated MOOC EEG study (six retained participants). The authors summarise that the analysis "reveals significant differences in brain responses among the learning stages within each task and among the learning tasks within each stage", but the pairwise tests show stage differences for online lectures (Stage 1 vs 2, Stage 1 vs 3) and virtual labs/quizzes (Stage 1 vs 2, Stage 2 vs 3), and task differences at Stage 1 and Stage 3 only. Post hoc power analyses were conducted.
"The statistical analysis reveals significant differences in brain responses among the learning stages within each task and among the learning tasks within each stage."
